The present work focuses on the characterization of the in-plane and out-of-plane behavior of a three-dimensional angle-interlock woven composite. In-plane tensile and compression tests, short beam shear tests and through-the-thickness compressive tests were carried out to assess the mechanical behavior of the composite material. The results are presented in terms of stress–strain responses, elastic moduli, failure strains and strengths. In addition, the material elastic properties were measured using an ultrasonic method. Results are compared with the values of the elastic properties determined by mechanical testing. A good correlation is observed which demonstrates the pertinence of this technique to measure in particular the through-thickness elastic properties of the material.

目前的工作重点是表征三维角度互锁编织复合材料的平面内和平面外行为。进行了面内拉伸和压缩试验、短梁剪切试验和全厚度压缩试验以评估复合材料的机械性能。结果以应力-应变响应、弹性模量、破坏应变和强度表示。此外，材料弹性性能使用超声波方法测量。结果与通过机械测试确定的弹性特性值进行比较。观察到良好的相关性，这表明该技术特别适用于测量材料的全厚度弹性性能。
